So that's what happens to the shells when Monsters hatch! Congles are great recyclers, and use a lot of drums. Eggshells can only stand so much pounding, after all. Congle is a triple-element Monster that is first unlocked on Cold Island. It is best obtained by breeding two monsters that have the combined elements of Cold, Water, and Air. By default, its breeding time is 12 hours long. As a Triple Elemental, Congle does not have a high coin production.
